Having an issue with mantaflow fluid simulation with flow object inside of another object
Your domain is too big with very low resolution (divisions) ... scale down Domain or increase Resolution.

Notes:

your mesh has double vertices, Merge &gt; by Distance M
instead of creating inner effector object by dupli banana and scale down (that results in penetrated object from original banana at the end) ...


... use Solidify modifier (before Fluid modifier) on original banana and use this object as Effector directly, so you get perfectly fitted inner mesh and simpler scene to work with

instead of Sphere for Inflow you can use Circle (or separated one banana loop), like that fluid comes from one direction (enable Flat) ... it depende how final result should looks like ...

Instead of separate animation of Inflow object you can Parent Ctrl+P Inflow object to animated Banana object to let move them together

in this example I set start of fluid sim cache at frame 34
